Fallen Catastrophe: Record of the Demon King's Cleansing of the World

He was once the most ridiculous dandy in the capital, spending money like water and playing the world, until he met her - that girl as pure as a spark, who taught him the meaning of holding a sword. But the greed of the noble family tore this purity to pieces. When he witnessed his beloved having his heart and soul ripped out, and the beauty blocking his sword from death, he finally understood: In this world, righteousness is hypocrisy, and compassion is a lie. Since there is no way in the world, he will wash the world with demon blood! "After today, there is no good or evil, only - my rules!" From a playboy to a demon king, from revenge to annihilation, this is a story of death and rebirth using hatred as flame and love as sacrifice.
